They pretend to be sunroom.com then it leads you to c thru sunrooms to then be sent an invoice of sunroom and patio rooms of san Diego.from a company supposedly in Corona. They will give a price and then say its your fault for not mentioning install and raise the price by a couple more thousands. John Scott is something for telling customers for not handing over thousands of dollars in checks immediately to him as "people who have a special place in hell" avoid at all costs.

They are paying to get good reviews as c thru, sunroom and patio rooms, sunrooms, they are a dba with no license and contract the work to workers who have had their licenses cancelled.

Critical: Professionalism, Quality, Responsiveness, Value This company is a SCAM! DO NOT waste your time and energy with these people. We've had non-stop problems with leaks since it was installed. This sunroom is such a headache and I wished we never installed it. $20,000 Down the Drain

This company is a scam. Ive had non stop issues with my sunroom only a year after purchase and the company will not reach back out. I have leaks from the roof which leaked thru our lights. This company is definitely fraudulent. Please save your time, money, and energy. They are going thru other fake company names now. Fourseason, socl quality, be very careful

I bought a brand new manufactured home that I was about to close escrow on. Bruce came out to give me an estimate on an inclosed patio. This proposal turned into an invoice without me knowing or him going over it with me. Job was on hold pending approval from the park and confirmation on the materials. Bruce collected way more then 10% he collected 25% and also wrote my credit card # down on paper. Told me verbally your good to back out approved or not. Very shady company with no values. Nothing was purchased or agreed upon. Bruce will not give me my $2100 back. Time to take them to the BBB and the License Board. Beware!

My husband and I worked personally with Mike on our custom designed sunroom. He ensured that we were in good hands. We are very happy with both the service and products we have received throughout our experience with C-Thru. Couldn't have asked for a better experience.

I ordered a custom sunroom enclosure for my property. It is truly a perfect match for my home. I would recommend the C-Thru products time and time again. They are the superior sunroom brand. Great company and fantastic products!

I am speechless! The pricing is phenomenal and the products are fabulous. The only negative I can take away from my experience with Cthru was their wait times. It felt like they were always getting backed up with orders due to such a high volume. Although, that was really out of their hands and they did the best they could do given the circumstances. Overall, very happy with my experience.

We purchased the Cthru products for such a bargain price! it's hard to pass up such a great deal. No wonder they're so crazy busy! We bought a couple months back and the build just finished up on Monday. It looks amazing!

I met with Bruce in nov. 2018 and gave him approx. 7K as down payment. It took over 7 months of nagging to get the anyone to my house to construct the sunroom. I, initially was told Duncan was the site manager but he made unkept promises and was not returning my calls. I finally got a new site manager and the job was completed with no invoices or warranty info provided.

My phone calls were not returned, Bruce's phone no longer worked. No one at c-thru wants to hear about it or be helpful. My project is complete, time will tell as far as quality (rain, etc). A customer should never have to fight for a project to be done or get invoices once it's done, I still have nothing for taxes. Look elsewhere until the contracting issue is resolved or you will have the same headaches.

Disclaimer. I think I dealt with a different vendor out of Encinitas. But gives the product a bad name. Their customer service sucks. The kids that came and installed were good, but don't pay them off until you make sure all correct. I had a couple issues but paid in good faith. Promises made to fix, but now the installer, Jason, appears to be dodging my calls for over a week and the C-Thru main office won't return my calls. So these may be different folks, but be careful.

It has become, for me, a sewing room, I love to sew, a reading room, and we can watch our television here if we want. But generally it's a relaxing room, and when we have company we come out here and entertain here. It becomes another extension of our home and our living.

We'd looked at various manufacturers and various dealers around town, and the one we liked best was built by C-Thru and we have been excessively please with both of our sunrooms from C-Thru.

The features we liked most about this room was the fact that it was going to be bright and sunny and that's what we wanted in a room.

We bought a house and we saw that we had a terrific view of the mountains from the rear. We wanted to accentuate this, and we did, and we're very pleased with the results.
